Microsoft has detailed Windows 8.1 - not a whole lot of information we didn't yet know from leaked builds, but this bit makes me happy: "The updated PC Settings in Windows 8.1 gives you access to all your settings on your device without having to go to the Control Panel on the desktop. You can do things like change your display resolution, set your power options, see the make and model of your PC, change the product key, let you run Windows Update, and even join a domain - all from PC Settings." Available as a preview late June, but no word on whether said preview release will be available for Windows RT as well.
